conventional engine

The core of the M-88 is studied to allow a Family of Engine going from 7.5 t to 11 t. That is that all these engines will have the same core but not the same compressor and so on. So with this core you can specify what thrust you want and adapt the engine. If you put the M-88 core in the Kavari as it is it will certainly have the Thrust that was initially specified, but you can increase it with changes.

Sorry for the noob question -
Will increasing the thrust with the same core means more wear and tear and less life for the engine??

not at all. If the airflow is correctly maintained and with proper compression, If you go thru the equation for jet engine thrust, you will realise that mass flow is the determining factor. A core must be able to withstand that kind of temperatures which are associated with such gas expansion.https://www.grc.nasa.gov/www/k-12/airplane/thrsteq.html

Just the way you will have a candle blowing off with too much of air or fails to burn with very little air, same is true for core of a jet engine also. A core cleared for 11ton thrust means, that it can withstand temperatures associated with air flow required to generate such thrust.

No it depend on what you change, for example to increase the thrust to 9 t for the UAE (it was not done) we developped a demonstrator M88-9 and for that we change the air mass flow from 65kg /s to 72 kg/s this modification doesn't change fiability and availability and general characteristics of M-88. But it change air inlet of Rafale so aerodynamic and RCS and then it cost to change the plane!
Now we have a new project of a M-88 8.3 t of thrust without changing the air mass flow. It doesn't change the plane, fine, but normally it change temperature pression and other parameters of the M-88 so normally it change the availability and fiability of the Engine! To maintain these qualities you need to improve technology, and it's because we have improved technology that it is now being considered to make this new version of M-88.

lol so, safran guys need 18 months time to upgrade m88 core and not to fix the Kaveri issue so why we are wasting our 1 billion offsets in Kaveri, french guys are simply using 1 billion dollar in upgrading their core engine

the new core will be build in india right from the scratch ............... so y not ?

“One of the most vivid illustrations (In Indo-Russian scientific partnership) is the KAVERI Indian aircraft engine. We have been involved in its development, modification and trials. The project is about to be over soon,” Alexander Mikheev, Director General of Rosoboronexport said in a statement today.

JSC Rosoboronexport pursues active cooperation with its foreign partners in the field of joint research and development works, the statement said adding that at present, the majority of company’s joint R&D projects are with India and China. The projects focus on cooperation in the field of space, naval, air defense and army equipment, as well as other hi-tech projects.

“At present Rosoboronexport and Russia’s strategic partners are running over 200 R&D projects, whose number increases with every passing year. The growth dynamics continues to be positive. For instance, the number of such projects had not exceeded 100 until 2014”, - Alexander Mikheev, Director General of Rosoboronexport further said in the statement.

Defenseworld.net comment: The information that Russia is collaborating with India on the Kaveri engine is indeed interesting.

The Kaveri engine, developed by the Gas Turbine Research Establishment (GTRE) was originally meant to power India’s home-made fighter jets but the project was put on the back-burner as it failed to meet deadlines.

Some media reports said that India is currently holding talks with the French company, Safran to explore the possibility to develop a 125kN thrust Class engine to replace current 123 kN Thrust Class AL-31FP turbofan engines developed by Salyut-HAL

Russian companies had also offered India its 142 kN thrust class AL-41F1S turbofan engines used in the Su-35 to replace current AL-31F turbofan engines, various reports said but the response of the Indian side was not known.

WTF! About to be completed!!!
Probably some misunderstanding.Maybe the original Kaveri program with Russia for Tejas is about to wound up ,not having met it's objective.

So we are working with France for Tejas engine.

Should not need anyone's help for Aura engine.

Working with Russians for Su30-MKI engine.

And what the hell was that report about engine jv from Britain/Rolls Royce?AMCA engine???

If all this is true,then that means we have as many eggs as baskets.
Thats hedging of our bets like we have never hedged before.Or maybe it's just the same phenomena of every one ready to help you,once you are about to achieve it yourself....

GoI want to reduce the risk of failure that is why multiple developments are running in parallel.

From my understanding of the article, work with the Russians consists of adapting the SU-30 MKI with the new Kaveri produced in collaboration between SAFRAN and HAL. The two countries are working on different things.

Yes,seems most likely.I just don't think "about to be completed" part is very accurate.....
